a 501 byte ASCII entry for asmcompo.org compo #10
by thefox <fuchs@runkkaajat.org> / aspekt 2004
-- what is it all about --
it's a simple flower in 501 bytes. only ascii characters are
used in the binary. this was accomplished by writing a loader
(in loader.asm) in ASCII which takes base64-encoded data as
input, decodes the data to memory and runs it.
-- build how-to --
the source code can be found under /src -directory
what's required to build this:
Microsoft (R) Macro Assembler ('ml.exe')
Microsoft (R) Segmented Linker ('link.exe', used in make
batch files as 'dlink.exe')
Microsoft (R) C/C++ Compiler ('cl.exe')
Microsoft (R) Incremental Linker ('link.exe')
C-compiler and incremental linker (32-bit) are required only
for building 256to64. you should be able to use any other
C-compiler also.
make_all.bat builds everything, first 256to64.exe, then
demo.com and finally loader.com (which is the final executable)
** DO NOT execute demo.com as its base address is not 100h **
the binary from make_all.bat is 513 bytes, here's how to create
a 501 byte binary:
first run make_all.bat as normal (or make.bat if you have
built 256to64 already)
use hex-editor on demo.com stripping out the last six
bytes (which should all be zeros)
run make_phase2_only.bat
if you want to build only 256to64, call make_256to64.bat
-- notes --
256to64 is just a quick hack. it *will* produce 'broken' include
files for some input file sizes. 'broken' means that the output
file has got a last line 'byte ""' which masm will give an error
about.
demo itself (both loader.asm and demo.asm) could've been optimized
a bit more also but reaching 512 bytes was enough for me this time.
-- public domain --
yes. do anything you want with these files.
i take no responsibility at all.
-- the binary --
just for the heck of it, here's the demo once more (starting from
'Z'-character, 'til the end of the file.
